RFID door lock security system using servo,buzzer & LED / or LCD

hey there!, in this post, you are going to learn about how to build an RFID based access control

system using Arduino. The system will only give access on scanning the right tag and on scanning the wrong tag, the system will deny access and buzzer will make a beep sound. There will be a master tag that will be used to add/remove other tags.

Component Required:

• Arduino UNO

• LED x2 (red,white)

• RFID sensor (MFRC522)

• Servo motor

• Jumpers

• buzzer

• Breadboard

• LCD 16x2

Circuit Diagram:

OR

Procedure:

• connect all component like servo, Buzzer, LED, RFID sensor same as circuit diagram

Upload the code to Arduino UNO:

here, link of code to download and run the program on Arduino IDE.
